invasion Specification of Letters Patent.

Application filed April 21, 1914. Serial No. 833,478.

Agricultural. ll/ilachine, of which the following is a specification.

The present invention relates to improve ments in agricultural machines, one object of the invention, being the'provision of a motor driven machine,in which a prime mover, preferably an explosion engine is employed, there being provided two clutch. actuated transmissions, one for actuating the tractor wheels and the other for actuating the cutter bar, in a mowing machine octhe harvesting mechanism in a harvester, thus permitting both to be operated independently, so thatregardless ot the speed at which the machine is moving, the speed of the other mechanism may be varied at will, this particular arrangement being a decided advantage over the structure in which the -mechanisms are operated from the tractor mechanism.

With the foregoing and other olnects 1n view which Will appear as the description proceeds, the invention resides in the combi nation and arrangement oi? parts and in the details of construction hereinafter described and claimed, "it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

in the drawings- Figure l is a side elevation showing the present invention applied to a mowing machine.

Fig. is a top plan view partly in section showing the prime mover, the two clutches and the means for transmitting motion to the cutter bar.

Referring to the dr'awings the numeral 1 designates the frame which is provided with the tractor wheels 2, each one oi which has attached thereto, the internal gear 3, which is operated by the pinion -icarried upon the transverse shaft 5. Upon "this transverse shaft 5 is a large bevel pinion 6, which in mesh at all times with. the small bevel pinion 7 carried upon the longitudinally disposed shaft 8. This shaft 8 is provided with a clutch member 9 which is manually controlled throutgh the lever 10 to be placed into and out of engagement with the coat-tingclutch member and fly wheel 11. This fly wheel is disposed upon the crank shaft 12 off the explosion engine 13. Thus the tractor wheels are operated as desired through the clutch.

A drum 14 is keyed upon and rotates with the shaft 12 at the opposite side of the engine to the fly wheel .11, this drum 14- being provided with a clutch face 15 for coaction gine and mowing mechanism hereinafter de scribed, while keyed upon one end of the shaft 22 is a disk to which there is eccentrically connected the pitman rod which is connected at 26 to operate the cutter bar 27 of the mowing mechanism 28. Thismowing mechanism is properly supported at one end by the bracket 29 and at the opposite end by the rod 29'.

As the movement of the clutch member carriage sprocket 19 is very slight, in practice being approximately one-quarter of an inch, the engine being so set that when the clutch is in engagement, the chain is driving the sprocket in alinemcnt, the throwing out of the clutch although moving the sprocket slightly out of alinement docs not atl'ect the chain to any nl'iprcciublc degree but in tact produces a slight braking effort so that the chain immediately stops.

lln order to properly steer the present icchanism so that the operator seated upon the scat S may have under his controh hoth thestecring and actuation of thc tractors and mowing niechanisn'i, the wheel do is journalcd in the torlr 31, a stem 10 being mounted in the frame 1 and carrying the worm gear 41 which is controlled by the small worm 42 actuated by the steering stati 43.

From the foregoing dcscriptiomit is evi-- mechanism controlled by the second clutch will be actuated imlependently, so that the lllatenteii. duly Q3, ninth,

crank shaft and tractor wheel a transverse finger bar projecting to one side of the frame and having its inner end disposed below the engine, a depending bracket carried by the-frame and attached to the innerend of said finger bar, a reciprocatory cutter bar carried by the finger bar, a counter shaft disposed between the horizontal planes of the frame and cutter bar at that side of the vertical plane of the crank shaft opposite the finger bar, a depending bracket carried by the frame in which the countershaft is journaled, a sprocket wheel carried by the for- Ward end of the crank shaft, a clutch for connecting said sprocket wheel and shaft,-a sprocket wheel carried by the counter shaft, a sprocket chain trained aroundsaid sprocket wheels, the rear end of said counter shaft having a crank, and a pitman connecting said crank and the inner end ofthc, cutter bar. i

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature in the presence of two witnesses.
